Factors affecting stresses in cortical bone around miniscrew implants: a three-dimensional finite element study.

Objective: To evaluate various types of stress in cortical bone around miniscrew implants using finite element analysis.

Materials And Methods: Twenty-six three-dimensional assemblies of miniscrew models placed in alveolar bone blocks were constructed using Abaqus (Dassault Systèmes Simulia Corp, Providence, RI), a commercial finite element analysis software package. The model variables included implant design factors and bone-related factors.

A comparison between a new 2-dimensional digital on-screen tooth measurement method with direct measurements.

Objective: To compare the accuracy and reproducibility of tooth measurements using newly developed software that gives 2-dimensional scanned images of dental setups with direct measurements using digital calipers.

Methods: This experimental study was performed at the Dental Laboratories of the Faculty of Dentistry, University of Jordan, Amman, Jordan from September 2010 to December 2010. Ten sets of acrylic teeth (10 upper and 10 lower arches) were used.

Burnout among the clinical dental students in the jordanian universities.

Background: The study aimed to evaluate the level of burnout among the clinical dental students in two Jordanian universities.

Methods: A total of 307 students from the two schools were surveyed using Maslach Burnout Inventory survey. Scores for the inventory's subscales were calculated and the mean values for the students' groups were computed separately.

Health status of the clinical dental students in the jordanian universities.

Background: Dental students are subjected to many stresses that may affect their achievement. The purpose of this study is to assess the mental and physical health of dental students in two Jordanian Universities.

Methods: A total of 265 dental students and 228 non-dental students from two Jordanian Universities participated in the study.

Frequency estimates and risk factors for postoperative morbidity after third molar removal: a prospective cohort study.

Purpose: The aim of this study was to estimate the frequency of postoperative complications after mandibular third molar (M3) surgery and identify the risk indicators.

Patients And Methods: This was a prospective cohort study of a sample of subjects having at least 1 mandibular M3 surgically extracted at a teaching hospital in Jordan. The predictor variables were categorized as patient, anatomic, and operative specific.

Application of Pont's Index to a Jordanian population.

The aim of this study was to assess the applicability of Pont's Index to a Jordanian population and to compare the results with those obtained from studies of different ethnic subjects. Dental casts of 144 Jordanians (71 males and 73 females; mean age, 15.5 years) with 'normal' occlusions were selected from the records of a random stratified sample of 383 Jordanian schoolchildren in the 10th grade.
